'Said' apron sections l9, are constructed with turned down ear portions 20 to give a finished appearveyer chain. At the rising curved juncture between apron sections IS, I have devised a special track 2| for the conveyer chain made of hardened steelthus-avoiding undue wear atapoint which would normally be subject to great friction. At' the top of the inclined straight juncture of apron sections I9, I have provided -a free pulley wheel 22 which is mounted on a shaft 23 carried by arms 24 projecting from the terminal frame 2.. The conveyer chain is led around said pulley and past or in contact with another free pulley 25 mounted on a shaft supported in arms projecting from'side frame 26 of the winding machine.

From thence the conveyer chain is led into a channel guide 21 forming a track supported by arms 28 depending from frame members I. Said channel guide is adapted to support the links of said. conveyer chain while permitting the pushers l5 to pass through out of contact with any support, thereby avoiding undue wear on said pushers l5. Said channelguide 21 is made to supportthe conveyer chain' 14 to a point proximate to the driving wheel H, as shown in Fig. 5.

Loosely attached to the frame 2 by means of v leather thongs 29 aretwo wooden guides 30, the upper ends ofwhich are spaced a relatively short distance apart while the lower ends are shaped as is shown in I igeand are held somewhat widerapart by :means of'leatherthongs 3| attached to the ears 20 by bolts 32.

-Attached across the upper portion'o'f said wooden'guides 30 by means of screws 33 is a plate 34, the lower end of which has a turned up portion 35. 7

Carriedby projectingjarms 24 is a U-shaped projecting frame 36 to the middle" portion of which is pivoted an inclined delivery slide 31, for the emptybobbins, extending proximate to the free pulley 22 and having, next to the conveyer chain itself, a V-shaped notch 38 slightly wider than the, small diameter of an ordinary bobbin, On shaft 23 are mounted two pulleys 39 over 'each of'which passes a'thong'dfli attached on its outer end to the inclined bobbin slide 31 Man. extension thereon ll and attached at the other end to a counterbalance weight 42.

Extending from the frame section 2 is a curved bumper bar 43 which serves to protect the mechanism at .the 1 delivery end of the conveyer from'damage due to such apparatus as may be usedto collect or carry away the deposited empty bobbins.

. Operation 7 Normally when; the winding machines are being usedthe conveyer will be moved by its driving sprocket wheel. However, since the bobbin conveyer-elevator is liable to'clog up with lint or other material or may conceivably become jammed in some way and since, in any machine around which human beings work-it is extremely advisableto provide instantaneous means of arresting moving ang have provided the slip-.

. drive, or safety latch heretofore described whereby when theload on the conve'ye'r'chain reaches a-predetermined maximum, the conveyer-chaindriving sprocket isautomatically disconnected from the ,source of power, and remains dis-- connected until manually reconnected by an operator who will have, in the meantime, determined and remedied the cause of the stoppage.

-It will be noted that the point at which the greatest friction will be found is the curved uprising portion. By driving my conveyer from the end opposite to this curved uprising portion, I materially reduce the strain on the conveyer chain at that point, thereby greatly lessening the friction from what it would be if the conveyer drivewere at the discharge end.

various number of such units.

Suppose agroup of empty bobbins is thrown onto theapron sections I1. They will tumble by gravity'down over the conveyer chain M, which will transport, with the assistance of its pushers, those empty bobbins which lie longitudinally over it, to the terminal section, where such longitudinally lying empty bobbins are elevated and deposited upon the bobbin slide for delivery into a. suitable receptacle.

In'case a bobbin does not first roll long-- itudinally onto the conveyer chain, it will be so agitated by thepushers, and. by the round headed bolts which attach the apron to the frame, that they will eventually come to lie longitudinally on the conveyer chain.

It may happen that quite a number of empty bobbins will pile up in the terminal section waiting to'be elevated by the pushers. In this casethey adually push the guides 30 outward toward the ears 2!). Since this-pushing tends to oppose gravity, there is alwaysa force tending to place the empty'bobbins in the middle of the terminal apron sections where they can be engaged by the pushers. 4 v

The plate 34, 35 tends to prevent bobbins from interfering with other. portions of the machine and tends to facilitate their orderly elevation. As the bobbins, one or more at a time, are delivered when the conveyerchain turns about pulley 22, they are dropped onto the bobbin slide where they slide off into a waiting receptacle. In case a bobbin should becomefljammed between the bobbin slideand said pulley, the inner end of the bobbin slide is readily forced downward as shown indotted'lines on Fig. 2, permitting the bobbin to fall clearof the machine.

.The bumper extending near the bottom of the machine protectsthe delivery mechanism and the other winding machine mechanism from injury through careless handling of thetruck or receptacle onto which the bobbins fall. It is evident that various changes maybe made in'the construction, form, and arrangement of the several parts without departing from thespirit and scope of my invention, hence I do not intend to limit myself to the particular embodiment herein shown and described, but WhatIclaim-is: 1;An empty bobbin conveyor for winding machines, means for actuating said conveyer and means for delivering the bobbins from said conveyer, comprising. a bobbin slide pivotedatits.
